Or, on second thought, maybe you didn't hear. With two other "disasters" dominating the headlines—the Times Square bombing attempt and the Gulf oil spill—the national media seems to largely to have ignored the plight of Music City since the flood waters began inundating its streets on Sunday. A cursory Google News search shows 8,390 hits for "Times Square bomb" and 13,800 for "BP oil spill." "Nashville flood," on the other hand, returns only 2,430 results—many of them local. As Betsy Phillips of the Nashville Scene writes, "it was mind-boggling to flip by CNN, MSNBC, and FOX on Sunday afternoon and see not one station even occasionally bringing their viewers footage of the flood, news of our people dying."

So why the cold shoulder? I see two main reasons. First, the modern media may be more multifarious than ever, but they're also remarkably monomaniacal. In a climate where chatter is constant and ubiquitous, newsworthiness now seems to be determined less by what's most important than by what all those other media outlets are talking about the most. Sheer volume of coverage has become its own qualification for continued coverage. (Witness the Sandra Bullock-Jesse James saga.) In that sense, it's easy to see why the press can't seem to focus on more than one or two disasters at the same time. Everyone is talking about BP and Faisal Shahzad 24/7, the "thinking" goes. So there must not be anything else that's as important to talk about. It's a horrible feedback loop.

Of course, the media is also notorious for its ADD; no story goes on forever. Which brings us to the second reason the Nashville floods never gained much of a foothold in the national conversation: the "narrative" simply wasn't as strong. Because it continually needs to fill the airwaves and the Internet with new content, 1,440 minutes a day, the media can only trade on a story's novelty for a few hours, tops. It is new angles, new characters, and new chapters that keep a story alive for longer. The problem for Nashville was that both the gulf oil spill and the Times Square terror attempt are like the Russian novels of this 24/7 media culture, with all the plot twists and larger themes (energy, environment, terrorism, etc.) required to fuel the blogs and cable shows for weeks on end. What's more, both stories have political hooks, which provide our increasingly politicized press (MSNBC, FOX News, blogs) with grist for the kind of arguments that further extend a story's lifespan (Did Obama respond too slowly? Should we Mirandize terrorists?). The Nashville narrative wasn't compelling enough to break the cycle, so the MSM just continued to blather on about BP and Shahzad.

If I sound like I'm condoning the media's inattention here, I'm not. My explanation is meant as a criticism. Given audience demands—especially at a time when traditional media companies aren't doing so well—it's impossible to avoid the stories with the most buzz and the strongest narratives. Nor should we. But urgency should be at least as important. In this case, the most urgent aspects of the oil spill and the Times Square attack had already been covered to death; the culprit was already caught, the containment was already underway. And yet we still kept rehashing each of those stories—and fighting about politics—while thousands of homes and business were destroyed and dozens of people died. That matters. Media silence means public ignorance, and public ignorance means fewer charitable donations, slower aid, and less political pressure. If that's not reason enough to cover the flood--to do our jobs--I don't know what is.
